How is Helium extracted at Sidney Lee Medical & Scientific Gases

In the news there has been plenty discussion surrounding the apparent lack of Helium accessible in Atlanta, GA and elsewhere around the world. This is a big concern seeing that this gas is utilized throughout multiple industries in Atlanta, GA. Uses for the gas include:

  • Magnetic Resonance Imaging (MRI)
  • Lifting gas – for hot air balloons and smaller recreational balloons
  • Breathing Mixtures – for deep-water diving and medical treatments
  • Welding Gas – utilized as a protective atmosphere

Helium is a result of radioactive decay in natural gas. Therefore since natural gas has the most volume of helium, most specialty gas laboratories like Sidney Lee Medical & Scientific Gases will extract Helium via natural gas. There are also limited amounts of helium in the air which can also be obtained, however the process for that is expensive and rarely used.

Usually helium is separated from natural gas through a cryogenic piping system. The natural gas is pressurized, and then travels through a sieve. During this scrubbing process, helium is separated from natural gas so that only crude helium remains. At this point, since the crude helium is only about 50% pure, more purification processes are warranted.

The temperature on the helium is reduced to -315 degrees Fahrenheit so that any remaining nitrogen or methane gases become liquefied and can be simply drained from the gas. The heat on the helium is then turned up and oxygen is added to the gas so that any remnant traces of hydrogen will mix with the oxygen creating water. Once the water vapors are formed, the mixture is decreased and the water is withdrawn from the mixture.

Once the water has been drained, the Helium then goes into vessels filled with tiny particles to further purify the gas (think of the carbon water filters in most homes in Atlanta, GA today). The process is repeated until the Helium is 99.99% pure specialty gas.

We at Sidney Lee Medical & Scientific Gases take this filtering process very serious as multiple industries, from the medical industry to the food & beverage industry, rely on our specialty gases for the best possible experience.
